Patient table apparatus

Abstract

A patient table apparatus having a pad for supporting a patient with at least two sections, a lower body section which will tilt with respect to an upper body section about an axis transverse to the pad. The apparatus includes a spring mechanism to impart an upward force on the lower body section against the force of gravity on the patient. A motor extends or retracts the spring mechanism and controls for the motor are provided whereby the amount of upward force on the lower body section may be increased or decreased.

What is claimed is: 
     
       1. A patient table apparatus having a pad for supporting a patient with at least two sections, a lower body section which will tilt with respect to an upper body section about an axis transverse to said pad, which apparatus comprises: a. adjustable spring means to impart an upward force on said lower body section against the force of gravity on the patient;   b. motor means to extend or retract said spring means;   c. control means to control said motor means whereby the amount of said upward force on said lower body section may be increased or decreased; and   d. means to lock said lower body section in place in a selected position with respect to said upper body section, said means including a lock bar pivotally attached at one end to said upper body section, a spring loaded pin adapted to engage with at least one opening near the opposite end of said lock bar, foot-operated pedal means to retract said pin from said lock bar, and a foot depressible wedge to retain said pin in retracted position from said lock bar.
